Archived Meteorological Data

Likewise there are currently 9 archived data sets available under the ARCHIVE DATA drop-down menu, all of which are stored on internal NOAA ARL computers.  All archived data sets except the NCEP/NCAR Global Reanalysis are obtained from NOAA's National Centers for Environmental Prediction (NCEP) and have been automatically converted to HYSPLIT compatible format.  The Global Reanalysis data sets are obtained in a similar fashion from the National Center for Atmospheric Research (NCAR).
